Title: Improvements in bearings and method of making the same
IPC: B22D19/08
Filed: 1932-10-07
Abstract: 407,120. Casting composite articles. GENERAL MOTORS CORPORATION, Detroit, Michigan, U.S.A. Oct. 7, 1932, No. 27994. Convention date, Feb. 12. Addition to 371,559. [Class 83 (i).] Moulds.-In the process of making bearings according to the parent Specification the bearing is cooled from the outside. As shown, a steel shell 5 has a plate 8 welded therto at its lower end, and a metal tubular core 10 is welded to the plate 8. After heating the shell 5, molten plastic bronze is poured in the space between the shell 5 and the core 10. The mould is then plunged into a bath of water, care being taken that water does not flow over the top of the tube 10. The bath has a grating 12 on which the mould stands. The rapid cooling from the outside acts to drive the lead and impurities in the bronze radially inwards so that the bronze is secured to the shall 5 by a layer of copper. After cooling, the article is machined to shape as indicated by the dotted lines in Fig. 3 so that the thickness of the layer of bronze remaining on the shell 5 is very small. Instead of a tubular cone 10, a solid core may be used, and the cooling may be accomplished by a jet of air or steam, or by immersion in a bath of molten lead or molten fusible salt.

Title: Improvements in high voltage circuit breakers
IPC: H01H33/16
Filed: 1969-06-04
Abstract: 1,261,592. Arc extinguishing in switches. GENERAL ELECTRIC CO. 4 June, 1969 [13 June, 1968], No. 28177/69. Heading H1N. In a reclosing high voltage A.C. circuit breaker having a plurality of series connected pairs of main contacts 25, 26, resistors are switched across the main gaps 22, 24 early in the reclosing operation, the effective total value of the parallel resistance being reduced later in the operation and prior to complete reclosure. Resistors 32, 42 may be successively connected across the main gaps 22, 24 by auxiliary switches 34, 40; alternatively parts of resistors 32 inserted by switches 34 may subsequently be shorted by other switches (50, 60) (Fig. 3, not shown); or the main contacts may be closed in two stages (Fig. 4, not shown). The circuit breaker may be of gas blast type as described in Specification 1,131,402 and has a reclosing gear which recloses the contacts within 40 cycles of the A.C. as described in U.S.A. Specification 2,582,027.

Title: Synchronization system for a data communication system
IPC: H04L7/02
Filed: 1961-08-03
Abstract: 981,399. Phase shift telegraphy systems. WESTERN ELECTRIC CO. Inc. Aug. 3, 1961 [Aug. 15, 1960], No. 28273/61. Heading H4P. In a synchronization system for a data communication system in which digital information is transmitted at a synchronous rate as phase shifts of a carrier wave, the synchronization frequency and the carrier frequency are such that each carrier phase change produces a unique pair of sidebands having a frequency difference equal to the synchronous rate, and means are included for recovering each frequency difference to serve as synchronization signals. In a system where serial data are converted into bit pairs which are used to effect the shift of a transmitted carrier wave during each signal interval by a multiple of 45 degrees, it is necessary that the ratio of the carrier frequency to the bit pair transmission rate (or synchronization frequency) be as any integer to the number four. With such a ratio the transmitted signal will contain upper and lower sidebands whose frequency difference is the same as the synchronization frequency (though the sidebands may not be of the same amplitude). Fig. 2 indicates the sidebands produced on a carrier frequency of 1750 cs. for the different possible bit pair combinations, showing the synchronizing frequency to be 1000 cs. The phase-shifted carrier is passed through filters 10 and 11, wherein the higher and lower sidebands are separated and passed to a balanced modulator 12, which may be a conventional diode ring modulator (Fig. 3, not shown), or a transistorized modulator as explained below. The output from the modulator is passed to a tuned network 13 where the difference frequency is extracted, this frequency then passing through a phase shifter 14 to compensate for phase shifts in the earlier circuits and then through a differentiating circuit 15 which yields the required synchronizing pulses. In the transistorized modulator (Fig. 4) the lower frequency sideband is passed through a phase-splitting stage containing transistor 41 to transistors 42 or 43, which are normally biased into saturation by positive potentials applied to their bases, thus short-circuiting the high-frequency sideband amplified through the transistor 40 to earth. The alternate switching on and off of transistors 42 and 43 by the low-frequency sideband switches the highfrequency signal alternately from one terminal to the other of the tuned circuit 13 at the lowfrequency rate, effectively producing therein the difference frequency. This may be taken off through a centre-tapped output transformer. Specification 981,400 is referred to.

In a getter pump an envelope having an inlet houses two co-operating electrodes 3, 8, Fig. 1, one, 3, of which is of gettering material and a third electrode 15. The initial discharge between cathode 3 and initiator electrode 8 is a pulse produced by opening a gap between electrodes 3, 8 by an electric motor-driven mechanism operating through bellows 20 and closing it again at the end of the pulse or by pulses from a car ignition coil, Fig. 2 (not shown), with a gap of adjustable length. The discharge between Ni gauze anode 15 and cathode 3 is also pulsed being obtained by the discharge of a capacitor 23 through a focusing coil 17 and the anode 15 in series. The cathode is made of gettering material such as Ti, Zr, Mg or Ca and has a hemispherical upper end 4, the arc initially from the end face of 4 being transferred to the side faces of 3. Some getter material is given off from the cathode and forms a layer on anode 15 and on the tube wall to serve as the active ion trapping layer. Mild steel discs shield the top and bottom of the envelope from gettering material. In either embodiment the cathode 3 may be movable instead of initiator electrode 8. The capacitor 23 may be replaced by a battery and switch. The magnetic means may be permanent or electromagnet.
